I agree. However, the fact that the current goes down a mA is less than 1%. With a Gunn diode, it has a negative dynamic resistance. An increase in voltage causes a drop in current. > Though the right question is what are they using as power detectors? I don't know. It is being discussed on ukmicrowaves A X-band Gunn Oscillator would almost certainly use WR90 waveguide which has a cutoff frequency of about 6.5 GHz, so one could not get any lower out of waveguide. > When the 2 are combined there could be a large lower frequency mix product. I don't see how it could propagate in waveguide. > Broad band detectors just collect all of the stuff and add it up. Does injection locking lead to increased frequency stability? I guess the effects of small temperature changes at one oscillator, which would ordinarily cause a change in frequency, might tend to opposed by the other. Only if they want to move in the same direction they shift more easily. > Regards > Paul > WB8TSL Dave _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
